2x60W Class D HiFi Bluetooth5.0 Power Amplifier Board QCC3034 TPA3221 Dual Channel Stereo Amplifier Module

Features:

- For APTX-HD UHD Bluetooth audio transmission protocol high fidelity amplifier chip.

- Low noise power supply processing.

- The design of the amplifier board is rigorous, and the materials used are professional.

- Add dedicated protection chips.

- Carefully designed, exquisite workmanship, adopting TG150 high temperature characteristics, matte black gold PCB.

- HiFi electronic materials: The audio circuit uses low-temperature drift high-precision resistors, and all surface mount capacitors use X7R and NPO low-temperature drift capacitors. Important circuits use 0.1% ultra-high precision low-temperature drift resistors, for WIMA HiFi film capacitors, for Sanyo ultra-low RES solid-state capacitors, for NCC ultra-low impedance high-temperature resistant capacitors, and digital amplifier specific shielded copper strip inductors.

- The whole machine adopts plug-in re-soldering technology, with smooth and firm solder joints, reducing the interference effect of the tip and making the sound quality purer.
